摘要

伴隨著科技的進步，無線通信系統已經從第一代發展到第四代。特別在前幾年，為了應對WiMAX (Worldwide Interoperability for Microwave Access)寬頻無線技術移動化的競爭，3GPP (Third Generation Partnership Project)啟動了移動通信系統(UMTS: Universal Mobile Telecommunications System) 的LTE (Long Term Evolution)項目，對以往蜂巢式細胞網路進行了革命性的演進。
蜂巢式無線通信系統的向前發展，吸引了越來越多的移動用戶，給蜂巢網路帶來了商機，另外客戶的要求也越來越高，帶來商機的同時也帶來了壓力，比如頻寬資源有限還有容量受限的壓力，本文基於這種情況下，提出了採用了新型的技術，可以有效地使資源使用效率大大的提升。
Device to Device (D2D)通訊系統是一種在LTE系統中通過重用蜂巢式網路使用者設備(Cellular user equipment ; CUE) 的資源來實現點到點通信的新型技術。首先本論文會先對D2D技術的原理進行介紹，並且比較D2D跟一些類似的技術。接著會引用一種降低干擾的方法[1]並加以修改和所提出資源分配演算法，使CUE及D2D整體效能不會因受到干擾而有所下降。

With the advances of technology, the wireless communication system has developed into the fourth generation. One of the schemes that is being researched and considered for 4G LTE Advanced (LTE-a) is the concept of Device to Device (D2D) communication. D2D also brings revolutionary progress in cellular system.
The D2D is a machine to machine standard by reusing CUE’s spectrum in LTE-a. Firstly, this thesis will introduce the concept of D2D and compare it with other similar technologies. According to [1], we then adopt an interference-mitigation method and resource allocation algorithm to ensure the whole performance of CUE and D2D would not degrade due to the interference. As a result, the severe-interfered area could be efficiently separated in our simulation.
